To all whom it may concern:

Be it known that I, ROBERT B. COCHRANE, a citizen of the United States, residing at Charlotte, in the county of Mecklenburg and State of NorthCarolina, have invented new and useful Improvements in Bottle-Openers, of which the following is a specification.

This invention relates to an improved bottle opener of the broad or general type disclosed in my Letters Patent No; 1,247 ,507 granted Nov. 20, 1917, such bottle openers being adapted to remove crimped caps from bottles, jars or they like and embodying a plunger for depressing the cap at its center and 'spreading it along its "edge, thereby freeing it from the bottle, and an ejector,

whose operation is correlated to that of the.

plunger, for'discharging'the cap from the machine. l' The invention proposes certain improved features of structure and relation'appertaining to the plunger, theejector and kindred parts; and the principalVV objects, of the 1nventionare to lfacilitate and lessen the cost of manufacture and to. provide a bottle opener which shallbe of compact form, shall have great" strength and eiicient 'wear resisting properties, whose working parts shall be inclosed p and therefore protected and more effectively lubricated, and whose individual parts' shall be easily accessible for the purposes ofre'pa'ir or renewal. Y

An embodiment of the invention is illustrated in the accompanying' drawing, whereinf 'Figure 1 isa view in side elevation, with certain parts in section, jof a bottle opener in which vthe features ofthe'invention are incorporated, the parts being shown in their normal positions."

The operating parts are inclosed'in a rcasi ing 1 which is lupright from-a Vsupporting base 2 having a bracket 3 at its rear end whereby the machine may be attached vto ya counter, table or other support.

YThev cap to be removed'from the bottle is` the crimps of the cap'have,^con sequent to the i l operation of theplunger, been disengaged from rthe usual'lbead"circumscribing they mouth" of the: bottlef As shown and preferred'such meansjincludes a frusto-conical sleeve 6 formed atthe frontend of Atheabase 2, an? expansible segmental frusto-coni'cal collar 7 inclo'sed inthe sleeve 5, and afsupportingv ring'v 8 secured to thev lower end of the sleeve 6 and upon whichl lthe collar 7 rests. The vcollar 7 includes a plurality,

preferably three, "of similar segmentsv 7a which are normally confined in mutual -adj acency to present an uninterrupted circular horizontalsection by Yspring locking means,

preferably an annular helical spring 9 which surrounds the segments 7'* with contractilek The neck of the bottle isv inserted from below through thecollar 7'whose Lsegments 7 ayieldradially to permit the movement, through and beyond them', of the bot'- 151e Call. 'Ehe/edge,V of 'the bottle cap' rests upon the upper edge or face ofthe collar 7 which therefore provides a supporting bearing for saidcap in opposition to the thrust exerted by the plunger 4.

The bottle cap is discharged from :the

machine through'a clearance 1,0 withjwhich the casing is formed, said clearance'being located between the guide and sleeve 6 and ment of vthe cap engaging element of the ejector, the upper Vface ofthe'eollar 7 is Hush y1.00 being open tothe front and sides of thecaswiththe upperV face of the'sleeve 6, the Said zio element or pusher 11 and av bell-crank opere atinglever 12.v The pusher 11 is horizontally disposed and movable and is formed at its front end with a cap engaging yoke 13 of increased width which is always disposed in the clearance 1'0. The shank of said pusher is disposed between the side walls of the casing 1 and is connected at its rear end by a knuckle oint pivot 14 to the depending arm of the bell crank lever 12,A the latter being mounted on a transverse pivot pin 15 which is secured inthe side walls ofthe casingl.

In order to correlate the operations of the cap releasing plunger 4 and ofthe ejector,A a second plunger 16, preferably located in the rear of the plunger 4, engages the forwardly projecting horizontal arm of the lever 12 and is operated inv synchronism withI the plunger 4. For this purpose the plungers i and 16 are preferably provided with a common operating head 17 from which they are pendent.- The ejector is maintained in operative relation to the plunger 16, andfor this purpose it is preferred that't-he depending arm of the bell crank lever 12 shall be Ibacked by a spring 18, preferably a helical spring, which is confined between said arm and the rear wall. 19 of the casing: 1. For convenience inr fitting the ejector in the casing, the rear wall` 19'is made removable and is therefore-provided at its upper end with a forwardly projecting attachment plate 20 which is secured by a screw 21, said screw being threaded in a transverse web of the casing. In case it should be desired to remove the ejector fromthe casing, this can be done very readily, the only' operation involved being the removal of the pivot pin 15 (which is threaded in one of the side walls of the casing); and-upon the removal of said pivot pin the ejector may be taken out by pulling it forward through the clearance 10. Upon the removal of the ejector the spring 18, if of helical form', may also be removed through said clearance. Said spring may, however, be taken out independently of said ejector by removing the rear wall 19 and pulling said spring rearwardly from Vbetween the side walls of the casing. j

kThe plungers 4e and 16 are operated by a cam 22 which engages the head 17 and, together with said head, operates in a clearance provided by ears 23 formed as upward extensions of the sideY walls of the casing, the cam being mounted on a transversepivot pin 24 fitted in said ears and being provided with a normally upright operating handleh25.- v

The various parts are maintained in their normal positions and are reset after each operation of the. machine by a springv 26 which, as shown and preferred, is of helical form andi surrounds. the plunger'li, bearing at its upper end against the head 17 and at its lower end against an abutment 27 formed as aninternal shoulderI of' theguide` into which thelower portion-of'said spring projects. In orderto limitthe'upward movement of the plungers andthe return movement of the cam, said cam and the head 17 are formed to provide mutual abutments' for cne'another;l andhfor this purpose the camv is provided with a transverse shoulder 28 which engages therfront face of` said head..

In case it should beV desiredl to remove the plungers 4f and 16this can be dene very readily, the only operation involved`7 being the removal of the'pivot pin 241i (which is threaded'in one'of the ears-23) and upon'the removal ofsaid: pivot pin, therv cam 22, plungers 4 and 16 and spring. 26 may be freely removed by liftingthem' from between thev ears 23;v

In the normal relation of the parts, the cap pusher 1'1 projects across the upper end of the socket 7 but presents n0- obstacle to the-movement of the cap througlrsaidl socket, owing to the-knucklefpivot 14: by which the pusher is connected tothe lever 12* and which enables said;V pusher toy yield freelyV in an upward direction as thel` cap is pushed upward beyond the socket.

ToA operate the machine the*y handle 25 is moved downward and rearward withv considerable force whereby to cause the cam 22 to lower the plungers 4 and 16. Said plungers in their downward movement vstore power in the respective springs 26 and 18; and the plunger 16, actingon the' bell crank lever 12, also effects the retraction ofthe pusher 11 toa position wherein itsv yoke 13 drops behind the cap; Immediately after theretraction of the pusher 111, the plunger 4- engages the cap`r dej'ire'ssi-ng its Ycenter and thereby causing the spreading of its e'd'ge'; the crimps of the' cap thus'being disengaged from the bead at they mout-h of the bottle.

During the downward movement of,Y the f handle 25 the bottle is helfd in the hand and when the cap is disengaged as described,A the gas with which the contents ofthe bottle may be charged, reacting against the cap will force the bottle downward, thereby complet-ely freeing it from the cap. If the' liquid is not carbonated the' bottle may be readily pulled downwardI from the loosened whoseyoke 13, sharply Vstriking the loose cap, discharges it from the machine.

'Ihe present invention although related as species to the invention disclosed in my above mentioned Patent No. 1,247,507, and hence of narrower purview nevertheless admits of certain modifications or variations from thev embodiment disclosed Which fall within the sco e of the appended claims.

Having ful y described my invention I claim.
